Volcano Calendar 2019: We're proud to present our 2019 volcano calendar: 13 different and attractive images of volcanoes, volcanic landscapes and phenomena taken during volcano tours over the past few years.

The Volcano Adventure Guide: Excellent information and background for anyone wishing to visit active volcanoes safely and enjoyably. The book presents guidelines to visiting 42 different volcanoes around the world.

San Cristobal volcano, also known as El Viejo, is the highest and one of the most active volcanoes in Nicaragua. It is located near the northwest corner of the country near the city of Chinandega, 110 km WSW of the capital Managua.
San Cristobal has had frequent small to medium-sized ash eruptions reported since the 16th century. When first observed by the Spanish in 1528, the volcano was in strong eruption and was described as sending "smoke" during the day and "flames" at night.

New eruptions occurred yesterday. The volcano produced a series of 7 small ash emissions between 06:45 to 11:43 am (local time). The explosions were very small and ash plumes only rose up to about 100 m above the crater. ...more

The new eruptions were followed by a rise in seismic activity in the form of tremor, which rose to about 3 times normal levels during the afternoon. The tremor pulse was still of relatively low energy and in itself not alarming, as the volcano experiences similar phases of elevated seismicity frequently, but given the recent activity, INETER warns that new explosions, possibly larger in scale, could follow with little warning and that air traffic should avoid the area of the volcano.Unconnected to the new eruptive activity, a small mud flow occurred at 17:10 local time on the lower slopes as a result of heavy rainfall, but did not cause damage.

More on VolcanoDiscovery:

Volcano Special Tours: We organize tours to particularly active volcanoes and during ongoing eruptions for extended observation time from various viewpoints. These trips, exclusively for very small groups, are often announced only at short notice and require fast travel and flexibility. Each trip is accompanied by a volcanologist from our team. Examples include: Kilauea (Hawai'i), Colima (Mexico), Krakatau and many others.

Tours to active volcanoes: Watching a volcanic eruption is one of the most impressive natural displays. We have a wide selection of tours to active volcanoes worldwide at different activity and difficulty levels.

Volcanic crisis at Sakurajima - updates: A strong earthquake swarm and increased inflation were detected in August 2015 and triggered authorities to raise the alert level, as volcanologists think that a larger eruption could follow. News and updates on the events can be found on this page.
